Method Details
-
clearInferred
Description copied from interface:InferencerConnection
Removes all inferred statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.- Specified by:
clearInferred
in interfaceInferencerConnection
- Overrides:
clearInferred
in classInferencerConnectionWrapper
- Parameters:
contexts
- The context(s) from which to remove the statements. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.- Throws:
SailException
- If the statements could not be removed.
-
commit
Description copied from class:InferencerConnectionWrapper
CallsInferencerConnectionWrapper.flushUpdates()
before forwarding the call to the wrapped connection.- Specified by:
commit
in interfaceSailConnection
- Overrides:
commit
in classInferencerConnectionWrapper
- Throws:
SailException
- If the SailConnection could not be committed.
-
addInferredStatement
public boolean addInferredStatement(Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:InferencerConnection
Adds an inferred statement to a specific context.- Specified by:
addInferredStatement
in interfaceInferencerConnection
- Overrides:
addInferredStatement
in classInferencerConnectionWrapper
- Parameters:
subj
- The subject of the statement to add.pred
- The predicate of the statement to add.obj
- The object of the statement to add.contexts
- The context(s) to add the statement to. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.- Throws:
SailException
- If the statement could not be added.
-
addStatement
public void addStatement(Resource subject, IRI predicate, Value object, Resource... contexts) throws SailException Description copied from interface:SailConnection
Adds a statement to the store.- Specified by:
addStatement
in interfaceSailConnection
- Overrides:
addStatement
in classSailConnectionWrapper
- Parameters:
subject
- The subject of the statement to add.predicate
- The predicate of the statement to add.object
- The object of the statement to add.contexts
- The context(s) to add the statement to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, a context-less statement will be added.- Throws:
SailException
- If the statement could not be added, for example because no transaction is active.
-
rollback
Description copied from interface:SailConnection
Rolls back the transaction, discarding any uncommitted changes that have been made in this SailConnection.- Specified by:
rollback
in interfaceSailConnection
- Overrides:
rollback
in classSailConnectionWrapper
- Throws:
SailException
- If the SailConnection could not be rolled back.
-
begin
Description copied from interface:SailConnection
Begins a transaction requiringSailConnection.commit()
orSailConnection.rollback()
to be called to close the transaction. The transaction will use the defaultIsolationLevel
level for the SAIL, as returned bySail.getDefaultIsolationLevel()
.- Specified by:
begin
in interfaceSailConnection
- Overrides:
begin
in classSailConnectionWrapper
- Throws:
SailException
- If the connection could not start a transaction or if a transaction is already active on this connection.
-
begin
Description copied from interface:SailConnection
Begins a transaction with the specifiedIsolationLevel
level, requiringSailConnection.commit()
orSailConnection.rollback()
to be called to close the transaction.- Specified by:
begin
in interfaceSailConnection
- Overrides:
begin
in classSailConnectionWrapper
- Parameters:
level
- the transaction isolation level on which this transaction operates.- Throws:
SailException
- If the connection could not start a transaction, if the supplied transaction isolation level is not supported, or if a transaction is already active on this connection.
-
flushUpdates
Description copied from interface:InferencerConnection
Flushes any pending updates to be processed and the resulting changes to be reported to registeredSailConnectionListener
s.- Specified by:
flushUpdates
in interfaceInferencerConnection
- Overrides:
flushUpdates
in classInferencerConnectionWrapper
- Throws:
SailException
- If the updates could not be processed.
-
statementAdded
Description copied from interface:SailConnectionListener
Notifies the listener that a statement has been added in a transaction that it has registered itself with.- Specified by:
statementAdded
in interfaceSailConnectionListener
- Parameters:
st
- The statement that was added.
-
statementRemoved
Description copied from interface:SailConnectionListener
Notifies the listener that a statement has been removed in a transaction that it has registered itself with.- Specified by:
statementRemoved
in interfaceSailConnectionListener
- Parameters:
st
- The statement that was removed.
-
addStatement
public void addStatement(UpdateContext modify, Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:SailConnection
Adds a statement to the store. Called when adding statements through aUpdateExpr
operation.- Specified by:
addStatement
in interfaceSailConnection
- Overrides:
addStatement
in classSailConnectionWrapper
- Parameters:
modify
- operation properties of theUpdateExpr
operation producing these statements.subj
- The subject of the statement to add.pred
- The predicate of the statement to add.obj
- The object of the statement to add.contexts
- The context(s) to add the statement to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, a context-less statement will be added.- Throws:
SailException
- If the statement could not be added, for example because no transaction is active.
